I can almost guarantee that in the actual trailer, or the movie, there will be a scene with a soccer mom or clueless guy at a redlight, then a TF pulls up, the guy looks over, sees that no one is driving, and does a big "WTF?"

Then maybe the thing drives off and transforms and winks at the guy... or some kid in the back seat is like COOOOL!

Scene opens at a remote truck stop. Stereo-typical trucker finishing his cofee. He pays his tab and heads out to his truck. We don't see the whole cab but the door is red.

Camera switches to view inside the cab. Stan Bush's "The Touch" is playing on the radio (I know it won't happen... but this is my vision). As he drives through a barren desert landscape a voice over starts.

Narrator: "Millions of years ago, they arrived."

Narrator: "Noble protectors, explorers of the cosmos"

Through the front window of the cab a jet fighter (whatever the hell Starscream is supposed to be) flys from behind towards the horizon. The sound of the low flying jet's engine cause the trucker to begin to swerve on the road.

Narrator: "A warrior race, bent on conquest"

The jet fighter circles in the distance and begins on a head on course to the truck. The trucker begins to panic and the truck begins to vere (sp?) off of the road.

Narrator: "In a world where things are not always as they seem..."

The truck steers itself back onto the road. The jet closing in on its apparent collicsion course.

Narrator: "... prepare to have your world...."

The truck jackknifes itself and the trucker rolls out safely onto the side of the road.

Narrator: "... Transformed!"

As the jet closes in more, we hear the transformation sound.

The camera quickly pans out to a view of Earth, the ominous robotic eye fades in from the background. The eye lights up.

The words "Our World, Their War" come up on screen.

Fades into the title.

Date flashes onto the screen.

THE END.

I'm not really sure if I expressed this as I envisioned it, but I don't see any actual robots (other than the eye) in the trailer, only the transformation sound.

Like any other car commercial, we see a seemingly normal car drive on the open road, taking curves like nobodies buisness. The announce begins his normal sports car narration when suddenly we hear the whine of a jet engine(or copter). The road is rocked with explosions as the car swerves and narrowly dodges them. The audience obviously knows now something wierd is going on. Then the car stops, transforms points up and shoots.

Autobots:
It starts with the camera circling a fancy sportcar, and suddenly it graciously (not as clunky as the real commercial) transformers into Jazz, who then begins to breakdance. When it ends, he smiles as he winks at the camera before transforming back to carmode, a narrator then saying: "The real Autobots, coming to Earth on 7-4-7."

Decepticons:
Starts out as a typical army commercial. Have the military cast in each shot, each looking heroic into the camera as they do their day to day jobs, a text saying things like "It's their job to..." "...Providing vital information..." "...Protect and serve our nation", stuff like that. Then the final scene is in Iraq with the entire military cast together, looking into the camera in a groupshot, and then the final message appears: "...And to be slaughtered by alien robots." Then the cast is blown away by a explosion behind them, and the camera pans up to reveal a F-22 flying away before returning, and then it transforms to reveal Starscream, closing up on his face to reveal his typical smirk before it blacks out and the text "They will make a stand against the Decepticons on 7-4-7."
